Please be sure to read the entire product description.
This is a used item with a replaced headband, earpads (cooling pads), and third-party battery for SONY WH-1000XM4.
◎Color: Black
◎As this is a used item, we have confirmed that the Sony | Sound Connect synchronization, sound output, noise cancellation, and Bluetooth are all functioning without issue.
The exterior has been cleaned, and the interior has been disassembled once to clean the noise-canceling microphone, which can cause a high-pitched noise.
The exterior has some minor scratches, but no noticeable damage. The battery, earpads, and headband have been replaced with new ones, so we believe they can still be used for a long time. Please judge from the photos.
◎This listing is for the main unit only.
◎Although we have confirmed the operation for this listing, please only purchase if you understand that this is a used item. This is why we are selling it at a low price. If you are looking for perfection, please purchase a new item.

No pet or tobacco odors.
